Definitions

  • the present invention relates to a process for the preparation of large laundry detergent particles.
  • WO9932599 describes a method of manufacturing laundry detergent particles, being an extrusion method in which a builder and surfactant, the latter comprising as a major component a sulphated or sulphonated anionic surfactant, are fed into an extruder, mechanically worked at a temperature of at least 40 °C, preferably at least 60°C, and extruded through an extrusion head having a multiplicity of extrusion apertures.
  • the surfactant is fed to the extruder along with builder in a weight ratio of more than 1 part builder to 2 parts surfactant.
  • the extrudate apparently required further drying.
  • PAS paste was dried and extruded.
  • Such PAS noodles are well known in the prior art. The noodles are typically cylindrical in shape and their length exceeds their diameter, as described in example 2.
  • US 7,022,660 discloses a process for the preparation of a detergent particle having a coating.
  • the present invention provides a coated detergent particle that is a concentrated formulation with more surfactant than inorganic solid. Only by having the coating encasing the surfactant which is soft can one have such a particulate concentrate where the unit dose required for a wash is reduced. Adding solvent to the core would result by converting the particle into a liquid formulation. On the other hand, having a greater amount of inorganic solid would result in a less concentrated formulation; a high inorganic content would take one back to conventional low surfactant concentration granular powder.
  • the coated detergent particle of the present invention sits in the middle of the two conventional (liquid and granular) formats.
  • the present invention provides process for the preparation of a coated detergent particle having perpendicular dimensions x, y and z, wherein x is from 1 to 2 mm, y is from 2 to 8mm (preferably 3 to 8 mm), and z is from 2 to 8 mm (preferably 3 to 8 mm), wherein the process comprises the following steps:
  • step (iii) The amount of water removed in step (iii) is commensurate with the amount of water added in step (ii); some water from step (ii) will likely be retained, for example as hydrated salts.
  • the amount of water removed in step (iii) is preferably from 50 to 100 wt % of the water added to the uncoated detergent particle in step (ii).
  • wt % refer to the total percentage in the particle as dry weights.
  • Compacting, briquetting and pelleting with roll type presses can be used to form shaped particles of a desired size and shape.
  • the product is densified by a screw feed arrangement and two, counter rotating rolls gently shape the material.
  • the profile of the rolls is such that precise shapes can be produced without material sticking to the rolls. Size and shape can be adapted to the application.
  • the product remains within the forming zone of the machine for only a short time and the product is produced at ambient temperature.
  • a pair of toothed rolls counter rotate.
  • the rolls draw the product in and press it out through the nozzles between the teeth.
  • the press nozzles can be bored directly into the press rolls or the rolls can be equipped with exchangeable nozzle plates.
  • the water soluble inorganic salts are preferably selected from sodium carbonate, sodium chloride, sodium silicate and sodium sulphate, or mixtures thereof, most preferably 70 to 100 wt % sodium carbonate.
  • the water soluble inorganic salt is present as a coating on the particle.
  • the water soluble inorganic salt is preferably present at a level that reduces the stickiness of the laundry detergent particle to a point where the particles are free flowing.
  • the amount of coating should lay in the range 1 to 40 wt % of the particle, preferably 20 to 40 wt %, even more preferably 25 to 35 wt % for the best results in terms of anti-caking properties of the detergent particles.
  • the coating is applied to the surface of the surfactant core, by crystallisation from an aqueous solution of the water soluble inorganic salt.
  • the aqueous solution preferably contains greater than 50g/L, more preferably 200 g/L of the salt.
  • An aqueous spray-on of the coating solution in a fluidised bed has been found to give good results and may also generate a slight rounding of the detergent particles during the fluidisation process. Drying and/or cooling may be needed to finish the process.
  • the thickness of coating obtainable by use of a coating level of say 5 wt% is much greater than would be achieved on typically sized detergent granules (0.5-2mm diameter sphere).
  • this surface area to volume ratio must be greater than 3 mm -1 .
  • the coating thickness is inversely proportional to this coefficient and hence for the coating the ratio "Surface area of coated particle" divided by "Volume of coated particle” should be less than 15 mm -1 .
  • the coated laundry detergent particle is curved.
  • the coated laundry detergent particle may be shaped as a disc.
  • the coated laundry detergent particle does not have hole; that is to say, the coated laundry detergent particle does not have a conduit passing there though that passes through the core, i.e., the coated detergent particle has a topologic genus of zero.
  • the hardness at the point of compaction is an interplay between the surfactant composition and the amount of water in the material being rolled.
  • Some surfactant systems have to have relatively low water content to have the requited threshold of hardness other surfactant systems can tolerate larger water content.
  • Hardness was measured in the following manner. A rigid probe of spherical shape is pressed into the test material at a particular velocity until a maximum load is reached. After a dwell - or hold-time at this load, the indenter is withdrawn from the material at a constant velocity. Once the raw data are processed, the indentation data consist of the compressive load on the indenter, W [N], and the total penetration depth, ht [m], into the material as a function of time during the three phases of the experiment; namely the loading phase, the hold phase and the unloading phase. The latter phase contains information about the adhesive behaviour.
  • the material is stored in a chamber which is kept at a constant 5%RH until they have stabilised.
  • a Novasina water activity instrument is used to check the RH of the granules.
  • the granular material is loaded into a 20mm diameter die and compressed with a load ok 10kN such that a "compact" is formed.
  • This compact then becomes the test sample for a sphere indentation test which is carried out under the following conditions.
  • a 3mm diameter synthetic sapphire sphere is pressed into the compact at a rate of 25 ⁇ m/s (check on Monday) until a load of 1 N is achieved.
  • This load is then held constant for 30 seconds (referred to as a creep segment) and then the sphere is removed from the compact at a rate of 10 ⁇ m/s.
  • the force and displacements are captured at a rate of 25Hz during the course of each experiment and stored for future analysis.
  • a standard series of tests would involve measuring the H values at 20°C and 5%RH. More compacts are stored at 18%RH, 33%RH and 50%RH and once stable at those conditions they are then measured, again at 20°C but with the RH kept at these conditions during the course of each test.
  • the coated laundry detergent particle comprises between 40 to 90 wt%, preferably 50 to 90 wt% of a surfactant, most preferably 70 to 90 wt %.
  • a surfactant preferably 70 to 90 wt %.
  • the nonionic and anionic surfactants of the surfactant system may be chosen from the surfactants described " Surface Active Agents" Vol. 1, by Schwartz & Perry, Interscience 1949 , Vol. 2 by Schwartz, Perry & Berch, Interscience 1958 , in the current edition of "McCutcheon's Emulsifiers and Detergents” published by Manufacturing Confectioners Company or in " Tenside-Taschenbuch", H. Stache, 2nd Edn., Carl Hauser Verlag, 1981 .
  • the surfactants used are saturated.
  • Suitable anionic detergent compounds which may be used are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.

However, the invention may also be of use for washing with soft water, either naturally occurring or made using a water softener. In this case, calcium tolerance is no longer important and blends other than calcium tolerant ones may be used.
  • Suitable calcium tolerant co-surfactants include SLES 1-7EO, and alkyl-ethoxylate nonionic surfactants, particularly those with melting points less than 40°C.

  • an aqueous solution of the water soluble inorganic salt can be performed using a slurry.
  • the aqueous solution preferably contains greater than 50g/L, more preferably 200 g/L of the salt.
  • An aqueous spray-on of the coating solution in a fluidised bed has been found to give good results and may also generate a slight rounding of the detergent particles during the fluidisation process. Drying and/or cooling may be needed to finish the process.
